Unit Information

Degree per second (°/s)

Definition: Angular speed equal to one degree per second.

History: Derived unit combining the degree of angle and the second of time.

Current Use: Used to express moderate angular velocities in engineering and physics.

Radian per second (rad/s)

Definition: SI unit of angular velocity equal to one radian each second.

History: Derived from base SI units of angle (radian) and time (second).

Current Use: The standard physics and engineering unit for angular speed.

Revolutions per minute (rpm)

Definition: Rotational speed equal to one full turn per minute.

History: Popularised by mechanical and automotive industries.

Current Use: Commonly used for speeds of engines, drills, and other machinery.

Revolutions per second (rps)

Definition: Rotational speed equal to one full turn per second.

History: Employed where high rotational speeds must be expressed.

Current Use: Used for turbines, centrifuges, and high-speed motors.

Radian per minute (rad/min)

Definition: Angular speed equal to one radian per minute.

History: Derived from SI angle and time units.

Current Use: Expresses slow angular velocities for astronomical and control applications.

Degree per minute (°/min)

Definition: Angular speed equal to one degree per minute.

History: Combines the non-SI degree with the minute of time.

Current Use: Used for slow rotations and navigation instruments.

Degree per hour (°/h)

Definition: Angular speed equal to one degree per hour.

History: Historically used in astronomy and surveying.

Current Use: Useful for very slow rotations such as Earth rotation or telescope tracking.
